    AC Delco Battery replacement

    Hello to all. I'm a newbie who just bought a 2006 Cadillac CTS - 2.8 L.

    The existing AC Delco battery is 4 years old and with winter just around the corner here in frigid Manitoba, I would like to buy a non-Delco replacement battery because I just don't like paying a GM dealership $250.

    The problems: The existing Delco battery has a battery blanket with the top cover tied down to its front side with a velcro strip. The location of the battery is at the top left corner just under the hood. The battery has its two terminals on the front of the battery facing me and not at the top like most car batteries. I'm not sure if I bought a non-Delco battery if the:

    (1) existing cable connectors to the terminals are long enough for a top connection rather than a side connection, and

    (2) top terminals of the brand new battery might touch the underside of the metal hood thus 'shorting' the battery.

    Can anyone here see any dangers in what I am proposing to do?

    Thank you.

    Re: AC Delco Battery replacement

    first off, welcome to the forums...

    now there are many threads on this same topic. a few people have been able to but a new battery in with the top terminals connected and everything just fine. i am not positive which batteries they went with, but it is possible. but to let you know, there are other battery brands out there that also have side battery terminals that are non AC Delco...

    I haven't measured the clearance, But GM didn't put this battery in for fun. I Expect that you run the risk of shorting yore battery using one with top poles. And that wouldn't be fun. The battery can explode or you get a fire.

    I don't know what state you're in, but by me you can buy delco batteries from certain parts stores without having to go to a dealership.

    Thank you to all for your responses and for welcoming me as a newbie here.

    I phoned all the battery stores and none of them carry AC Delco. It seems that GM has a stranglehold monopoly here in Winnipeg, Manitoba, Canada.

    OK, being that the hood has practically zero clearance between its underside and the top surface of the new battery terminals, I must go with a non-Delco battery with side terminals (which are hard to find). The Sears Diehard batteries are also terminals. The Wal-Mart Eveready batteries I was told by the Wal-Mart guy won't do for a Cadillac 2006 CTS.

    Re: AC Delco Battery replacement

    dont let them tell you a certain battery will or wont work over the phone. you should probably go and look at it and verify for yourself. a few other people have been told that certain batteries wouldnt work, they bought them anyways and the battery worked like a champ...

    Re: AC Delco Battery replacement

    So the moral of this thread. If the shoe fits, wear it.

    If the replacement battery is the same dimentions, within a certain tolerance, side terminals and above 660CCA. Then it will work.

    Re: AC Delco Battery replacement

    yea I went to walmart and crappy tire and eyeballed up a few "group 78" side terminal batteries, they are a very close size ( there's no reason to buy a top terminal one) , it installed perfectly and the car starts better than ever, don't overcomplicate this, it's just a battery.

    Re: AC Delco Battery replacement

    Maybe it was just my car, but I needed a battery with about 800 CCA. When the engine is hot and you try to start it the 660 CCA was giving me intermittent start problems.

    I prefer to let the battery die and get the AAA battery service to replace it. They only charge about $40 more than picking one up yourself: and they come to your house, change it, replace corroded leads and give a 6 year warranty.

    Re: AC Delco Battery replacement

    I replaced the original with a Exide TrailBlazer 75-2A, side mount, 910amps, 730cc. It's not as wide, but a hair higher than stock so I didn't use the cover. Purchased at Tractor Supply. Don't remember the price, maybe around $80.
